Cook vermicelli in a large pot of boiling water according to package instructions; drain and rinse with cold water. Drain well and transfer to a large bowl.

Heat 2 Tbsp. oil in a medium skillet over medium-high heat; add shallot and cook, stirring, until brown and crisp, about 3 minutes. Using a slotted spoon, transfer shallot to a paper towel–lined plate and season with salt.

Wipe out skillet and heat remaining 1 Tbsp. oil over medium-high heat. Add scallions, garlic, and ginger and cook until fragrant, about 30 seconds. Transfer to a large bowl and let cool slightly.
